Pull request overview

This PR hardens the data-table cell editor host against mid-edit editor-type changes by rendering the column editor as a real React component (so hooks are owned by the editor’s fiber), and it updates the test environment to support selector escaping in jsdom.

Changes:

• Render renderEditCell via <EditCell /> (instead of invoking it as a plain function) to avoid React hooks-order crashes when the editor implementation swaps during an edit.
• Add a regression test proving editor swapping (hookless → hook-bearing) remounts cleanly and preserves the in-progress draft row.
• Add a minimal globalThis.CSS.escape shim in the jsdom test setup to support selector construction.
